My understanding was that you could change them yourself using either the iPhone Configuration Utility or http://www.unlockit.co.nz. Has something changed in that regard?
Good to know, thanks for the info. Is there no way for carriers to apply these settings directly? I know Bell did some tinkering on my iPad when I got a SIM from them while traveling in Canada, but I don't know if it was anything more advanced than what the user can access.
